What to Do When Spider Plant (Chlorophytum comosum) Gets Pests? 4 Pest and 3 Disease Control Methods
As a type of spider plant, the green-leaf spider plant has strong adaptability, so it is easy to grow and not prone to pests and diseases. However, when growing plants indoors, for various reasons, they inevitably contract diseases and get infested by pests, and in this respect the green-leaf spider plant is no exception. So, what should you do when the green-leaf spider plant gets pests? Below are 7 pest and disease control methods for the green-leaf spider plant. Follow along with the editor to take a look.
I. When the green-leaf spider plant gets pests, spray with pesticide
Because the green-leaf spider plant looks beautiful and can also absorb harmful gases such as formaldehyde, it is grown indoors by many people. But during cultivation, due to situations such as waterlogged potting soil and poor ventilation, it will attract pests and diseases. As for what to do when the green-leaf spider plant gets pests, it is actually very simple: confirm the pest, then spray the corresponding pesticide to solve it.
II. Pest and disease control for the green-leaf spider plant
1. Scale insects
When the plant clump is dense and ventilation is poor, the green-leaf spider plant is prone to scale insects, which attach to the leaves and cause them to lose their luster. Symptoms of infestation: the leaves of the green-leaf spider plant turn yellow, and in severe cases the entire plant will die.
Control method: Move the plant to a ventilated place, cut off the diseased leaves, then spray a dedicated insecticide, such as 40% omethoate diluted into a 1000-times solution or 50% malathion diluted into a 1500-times solution; if there are relatively few scale insects, you can dip a laundry detergent solution to wipe off the insects.
2. Aphids
The main pest of the green-leaf spider plant, it mainly harms leaves and buds, sucking large amounts of sap and causing poor plant growth. Because aphids reproduce in large numbers, they are usually densely packed when discovered, which is not only frightening but also very disgusting.
Control method: After discovering aphids, you can take manual aphid control by brushing off the aphids with a writing brush or a bristle brush and burying them in the potting soil; in addition, you can also use 50 grams of fresh chili peppers or dried red chili peppers, add 30 to 50 grams of water, boil for about half an hour, and spray the filtrate on the parts infested by aphids.
3. Whiteflies
One of the common pests that infest the green-leaf spider plant, it is tiny in size and reproduces quickly, parasitizing the phloem of the green-leaf spider plant and sucking its sap. Whiteflies are generally hard to spot, and once discovered they are in a large swarm; by then the plant has already had a large amount of sap sucked away and is very weak.
Control method: After discovering whiteflies, pesticide should be sprayed immediately for control. The pesticide can be 25% phosmet emulsifiable concentrate 1000-times solution, or 40% omethoate 1000-times solution. The best time to spray is in the early morning when adult whiteflies are less active.
4. Red spider mites
Besides scale insects, aphids, and whiteflies, red spider mites are also one of the pests and diseases of the green-leaf spider plant, mainly harming the plant's leaves. After infestation by red spider mites, the diseased leaves of the green-leaf spider plant initially show small yellowish-white spots, gradually turn red, then spread to the whole leaf, and even cause the leaves to curl, wither, yellow, and fall off.
Control method: After discovering red spider mites, you can use 40% dicofol emulsifiable concentrate 1500-2000-times solution for spray control, spraying once every 7 days, 2-3 sprays is enough, and the effect is good.
5. Root rot
The common disease of the green-leaf spider plant is generally root rot, which is caused by waterlogged potting soil and poor ventilation. Symptoms: the roots rot, and the leaves wither, yellow, and fall off until death.
Control method: After discovering the above symptoms, you can spray 50% carbendazim wettable powder 500-times solution, or directly drench the roots with it, once a week is enough; in severe cases, pull out the green-leaf spider plant, remove the rotten root parts, change the soil and pot, and replant.
6. Anthracnose
This disease mainly occurs under conditions of high humidity and stuffiness, waterlogged flower pots, overly dense plant clumps, and poor ventilation, and the affected part is the leaves. Symptoms: the diseased leaves show yellow-brown sunken small spots, which then expand into dark brown round spots, the leaf tips dry up, and then the whole plant dies.
Control method: Cut off the diseased leaves and burn them in a concentrated manner to reduce the source of disease; in severe cases, spray 50% carbendazim 1000-times solution or 70% thiophanate-methyl 1000-times solution for anti-rot control, and it will take effect after 2-3 times.
7. Leaf blight
Under conditions of relatively high environmental temperature, relatively high humidity, and poor ventilation, the green-leaf spider plant can also contract leaf blight. Symptoms: the leaves of the green-leaf spider plant first turn yellow, then become brown diseased spots, and finally spread to the entire plant.
Control method: When the above symptoms are found, use 70% zineb diluted into a 600-times solution for spray control, once every 15-20 days, and it will take effect after 2-3 times.
